Mirena - period pains for 3 months no blood!?

For 2 yrs I have suffered from severe abdominal pain, in Oct this year it was discovered I had endemtriotis, which was successfully taken out, however the surgeon fitted me with 2 mirenas 3 months ago, because I have a bicournate utuerus.Since then I still have horrendous abdominal pain (taking tramadol). I have all the symptoms of a period, bloated tummy, sore breasts, cramps and intercourse is incredibly painful nearly all the time. During this time there is no blood. The pain is agony, I have been suffering for 2 yyrs... please help I'm 23 yrs old and very much worried
